This sounds a bit like what Solaris "Boot Environments" have
been designed for. Look at FreeBSD's beadm (sysutils/beadm).
This would allow you to install the new OS "in parallel" to
whatever you already have installed, and then boot into that
new environment. If it works as intended, the remains of the
old system can be discarded. Just make sure you set the ZFS
flags properly (what to boot, also check the mountpoints).
